目的 为体侧下部筋膜链的存在提供解剖学证据。  方法 选择国人成人尸体下肢标本20例，解剖并观察在腓骨长肌筋膜与髂胫束（ITT）之间筋膜的连续性。对其普遍性的特征作出描述及评估其连续性。若能观测到两者间存在明显的解剖学的连续性，则通过对两者施加一定的拉力来测试该结构对张力的传导能力。  结果 发现了髂胫束与腓骨长肌筋膜之间的间接联系：在所有解剖的下肢标本中，ITT与小腿筋膜连接稳固，而后者与腓侧肌筋膜几乎不可分离。对ITT施加张力会引起小腿筋膜以及腓骨长肌筋膜之间的局部运动。  结论 髂胫束与腓骨长肌筋膜连接稳固，提示其可能在张力传导中起作用。

Objective To provide evidence for the presence of the lower body fascia chain.   Methods Totally 20 cases of Chinese adult femur were selected, and the anatomy was performed to observe the continuity on fascia between periosteal fascia and iliotibial tract (ITT). Judging the generic character and the degree of continuity of them. If there was a significant anatomical continuity between them, the tensile strength of the structure is tested by applying a certain tension to both.   Results First, an indirect link between the iliotibial tract and the fibular myofascial fascia was found: in all anatomical lower extremity specimens, the iliotibial bundle (ITT) was structurally connected to the fascial fascia, which was almost inseparable from the fibular fascia. Second, the application of tension to the iliotibial tract (ITT) could cause local movement between the fascia of the calf and the periosteal fascia.  Conclusion Iliotibial tract and fibular long muscle fascia are connected firmly. The stability of the connection suggests that it may play a role in the conduction of a certain tension.
